After driving 800 for over 10 years, now in the driving seat of WagonR i too fell the same trouble, but as many has suggested experience plays a big role. only the initial 50~ km i had the trouble, still i play it safe. stopping at a safe distance, sometimes the taxis in back blare their horn to move but i always keep distance.
there is one more trouble, when entering a deep pothole you can't judge the rubble or anything, adding to that my friend (MASS SA) has adviced me to keep out of potholes with loose stones as the engine bay (not sure) is aluminium not steel like 800, so if by chance a stone hits it it will be damaged.
so i am planning to install a front camera, i already have a reverse camera (my wife insisted on it, in case she drives) the LCD has two inputs, planning to install one in the Front.
kindly put in your suggestions.
